Thaks, Richard. :-) Prof.Tobias: "There are other theories, including AAT,
but my rejection of the savanna hypothesis did not mean that I was
automatically espousing the AAT (pace Holloway). The unseating of the
savanna hypothesis is one issue; its replacement by some other hypothesis to
"explain" bipedalism and uprightness is a separate issue."

Tobias is right here IMO: AAT does not explain bipedalism. AAT does,
however, explain body alignment. Bipeds don't need to be "upright":
kangaroos, dinos... It's about time the different elements of human
locomotion are going to be considered separately instead of throwing
everything in the basket "bipedalism", which doesn't say much (eg, Oreopith
has been claimed to have been bipedal). Rather, we must consider
2-leggedness, plantigrady, body alignment, very long legs, valgus knees,
straight hips-knees (vs BKBH), etc. Some bipeds are short-legged
(penguins), some are not plantigrade (ostriches), most are not "aligned"
(kangaroos), many have bent-knees-bent-hips (indri on the ground), etc.
